About These Birds
Bicknell's Thrush
Bicknell's Thrush is a vulnerable, secretive thrush that breeds in dense montane spruce-fir forests in the northeastern United States and adjacent Canada. It has brown upperparts, spotted buff-white underparts, and a faint yellowish base to the lower mandible. It winters in the Caribbean, particularly Hispaniola, where it is threatened by habitat loss at both ends of its migration.
